The increasing share of variable renewable energy (VRE) generation poses challenges to power systems. Possible challenges include adequacy of reserves, planning and operation of power systems, and interconnection expansion studies in future power systems with very different generation patterns compared to today. To meet these challenges, there is a need to develop models and tools to analyze the variability and uncertainty in VRE generation. To address the varied needs, the tools should be versatile and applicable to different geographical and temporal scales. Time series simulation tools can be used to model both today and future scenarios with varying VRE installations. Correlations in Renewable Energy Sources (CorRES) is a simulation tool developed at Technical University of Denmark, Department of Wind Energy capable of simulating both wind and solar generation. It uses a unique combination of meteorological time series and stochastic simulations to provide consistent VRE generation and forecast error time series with temporal resolution in the minute scale. Such simulated VRE time series can be used in addressing the challenges posed by the increasing share of VRE generation. These capabilities will be demonstrated through three case studies: one about the use of large‐scale VRE generation simulations in energy system analysis, and two about the use of the simulations in power system operation, planning, and analysis.

使用时间序列仿真工具评估可变的可再生能源发电对电力和能源系统的影响

可变可再生能源(VRE)发电所占份额的不断增加对电力系统提出了挑战。可能的挑战包括储备的充足性,电力系统的规划和运行以及与今天相比发电方式截然不同的未来电力系统中的互连扩展研究。为了应对这些挑战,需要开发模型和工具来分析VRE生成中的可变性和不确定性。为了满足各种需求,这些工具应该是通用的,并适用于不同的地理和时间范围。时间序列仿真工具可用于在VRE安装不断变化的今天和将来的场景中建模。可再生能源的相关性(CorRES)是丹麦技术大学开发的一种仿真工具,能够模拟风能和太阳能发电的风能系。它结合了气象时间序列和随机模拟的独特组合,可提供一致的VRE生成和预测误差时间序列,并具有分钟尺度的时间分辨率。这种模拟的VRE时间序列可用于解决由VRE生成份额增加带来的挑战。这些能力将通过三个案例研究得到证明:一是关于在能源系统分析中使用大型VRE生成模拟,二是关于在电力系统运行,规划和分析中使用模拟。它结合了气象时间序列和随机模拟的独特组合,可提供一致的VRE生成和预测误差时间序列,并具有分钟尺度的时间分辨率。这样的模拟VRE时间序列可用于解决由VRE产生份额增加带来的挑战。这些能力将通过三个案例研究得到证明:一是关于在能源系统分析中使用大型VRE生成模拟,二是关于在电力系统运行,规划和分析中使用模拟。它结合了气象时间序列和随机模拟的独特组合,可提供一致的VRE生成和预测误差时间序列,并具有分钟尺度的时间分辨率。这种模拟的VRE时间序列可用于解决由VRE生成份额增加带来的挑战。这些能力将通过三个案例研究得到证明:一是关于在能源系统分析中使用大型VRE生成模拟,二是关于在电力系统运行,规划和分析中使用模拟。
